DRAIN FOR STALLS.

SEECIFICATION forming part of Letters Patent No. 502,004, dated July 25, 1893. Application filed February 26, 1892. $erial No. 422,922. (No model.)

To all whom it nuty concern:

Be it known that I, MARTIN LOGAN, of New York city, in the county and State of New York, have invented a new and Improved Drain for Stalls, of which the following is a full, clear, and exact description.

My invention relates to an improvement in drains for stalls, and the object of the invention is to provide a neat, simple, economic and convenient device, capable of being easily applied to any stall and which will thoroughly drain the same.

A further object of the invention is to provide a drain which will not easily become clogged and fouled, and one which can be expeditiously cleaned if clogged.

Another object of the invention is to construct a drain which will not be injurious to the feet of stock, and which will be entirely free from nails, screws, sharp bars, or any surface liable to lacerate stock, and wherein also the tread bars of the drain may be easily and quickly removed from the body of the drain, and both cleaned and the bars replaced without in the least injuring the floor of the stall or removing any portion of the floor or fixtures of the stall.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a partof this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of a single box stall, illustrating the application of the drain thereto. Fig. 2 is a transverse section through the drain and a portion of the floor of the stall, the section being taken practically on the line 2--2 of Fig.1. Fig. 3 is a longitudinal section through the drain anda transverse section through the culvert connected therewith, the section being taken practically on the line 3-3 of Fig. 2. Fig. 4 is a perspective view of the body portion of a drain adapted for use in a single stall. Fig. 5 is a plan View of a double box stall, illustrating the application of the invention thereto. Fig. 6 is atransverse section through the stall and through the drain as shown in Fig. 5 practically upon the line 6-6 of said figure. Fig. 7isa longitudinal section taken practically on the line 7-7 of Fig. 5; and Fig. 8 is a perspective view of the body portion of a drain adapted especially for use in a single stall, which drain is a modification of that shown in Fig. 4, differing butslightly in construction therefrom.

The base A of the drain is preferably constructed of metal, is ordinarily essentially rectangular in cross section, and consists of a plate provided at two sides and at one end with a marginal flange 10, the said flange being preferably made angular in cross section, and a series of ribs 11, produced upon the upper face of the plate. Each rib is provided in its upper face with a longitudinal U,V-shaped or semi-circular groove, forming thereby a series'of gutters 12; and the outer faces of the ribs are preferably made perpendicular, creating thereby a series of channels 13, essentially rectangular in cross section, and as the flanges of the body plate are at the sides and at one end only of the latter, both the channels and the gutters are closed at one end and open at the other. The side flanges form one wall of the outermost gutters, and at the front end of the body plate of the drain a downwardly-extending lip 14, is formed, which is either integral with or attached to the said plate, as in practice may be found most desirable.

In each channel 13 a tread bar 15, is inserted, the said tread bar being somewhat T-shaped in cross section, comprising a head which is above and rests upon the ribs, and a shank which entersa channel 13 between the ribs, as shown in Fig. 2. The drain is ordinarily placed at or near the center of the stall, the flooring B of the stall being out away or so laid as to form an opening 16 for the reception of the drain. The flooring at the inner end of the opening is provided in its under face with a rabbet 17, and a corresponding rabbet 18, is formed in the upper face of each tread bar at its inner end to mate the rabbet in the flooring, thus effecting virtually a smooth table joint and a decidedly perfect lock. The outer end of each tread bar, that is the head section'of the bar, is preferably beveled, as shown in Fig.3 at a.

When the drain is placed in the opening 16 in the floor of the stall, the upper member of the flanged portion 10 of the drain body is made to engage with the under face of the boards forming the side walls of the opening; and the height of the tread bars is such that their upper faces will be practically flush with the upper surface of the floor when the drain is in position.

In placing the drain in a single stall the,

body of the drain is ordinarily carried over the inner edge of the main drain or culvert D of the stall; and the tread bars are held in position by the cover D of said culvert, which cover is beveled at one side to rest upon the beveled surface a of the tread bars, as shown in Fig. 8. Thus the upper face of the cover of the culvert or main drain maybe flush with the upper faces of the tread bars; but the gutters 12, are led directlyinto the culvert or main drain below its cover, and as the lip 14: of the stall drain engages with and is made to neatly conform to the inner face of the culvert at its inner upper edge, all liquid will be directed into the culvert, and can not possibly work under the drain,or the flooring contiguous to the drain.

It is obvious that matter collected into the gutters 12 will readily find its way into the main drain or culvert, and that when it is desirable to remove the tread bars in order to clean the gutters should they become clogged, it is simply necessary to remove the cover from the main drain or culvert, whereupon the inner ends of the tread bars may be drawn from beneath the flooring and'lifted vertically upward out of engagement with the base. The entire surface of the base will then be exposed to View, and may be readily washed out or otherwise cleansed.

I desire it to be distinctly understood that I do not confine myself to the exact formation of the walls of the channels 13, as the walls of the channels maybe made to flare outward slightly, but it is preferred that the said walls be substantially vertical. The tread bars may be made of any suitable or approved material, but Wood is preferred.

In the form of drain used in a single stall, the tread bars are made to run longitudinally of the body; whenever the drain is to be used in a double stall, however, as shown in Fig. 5, the order of the arrangement of the tread bars is usually reversed, that is, they are made to extend transversely of the body plate, as two drains in this form of stall are employed, one located at each side of the center; the culvert D is placed centrally of the stall, and the lip 14 of each drain plate is formed at its inner side instead of at its outer end.

both sides of the stall or from both drains.

The culvert when centrally located is made to pitch or incline at its bottom downward in Thus the one culvert carries away the refuse from 1 is located between two drains both side edges of its cover will be beveled so as to engage with the ends of the tread bars of both drains as shown in Fig. 6.

In Fig. 8 a slight modification is shown in a drain adapted for use in a single stall. This modification consists only in the fact that the culvert D, is formed integral with the main or body plate; therefore, in this instance, each drain will be provided with a main gutter or culvert of its own to receive fluid or material only from the drain with which it is connected, and the culvert D when made in connection with the drain proper is provided with an offtake channel or opening D The form of drain shown in Fig. 8 possesses this advantage, namely, the refuse matter from one stall will not pass in front of the drain of the stall next to it, and thus the end stalls in a row will be prevented from the possibility of flooding, as might happen in the construction shown in Fig. 4, where all the refuse matter from one side of the stable must pass by said end stalls for final exit.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a stable drain, a supporting plate having ribs formed on its upper surface to form alternate drain-channels and tread-bar receiving grooves, said tread-bar grooves having substantially vertical sides, and the T- shaped tread-bars vertically removable, substantially as and for the purpose specified.

2. The combination, with a culvert and a flooring having an opening therein, of a plate adapted to fit in and close the floor opening "as described, one end of the plate extending to the drain and the said plate being provided in its upper face with a series of gutters and channels and tread-bars located in the channels and movable therefrom, the said tread-bars being stepped at one end to extend beneath the flooring and provided with a beveled surface at their opposite end over which the beveled edge of the cover of the drain rests, whereby the tread-bars are held in position and may be withdrawn from the plate only when the drain-cover is removed from engagement with them, substantially as described.
